I really enjoy my 70D but wonder if the 7D would have better IQ. When I look at DxO scores for these two, it's pretty much a dead heat. Anyone out there have first-hand experience comparing the two? Thanks in advance.
7D vs. 70D: Which has better image quality?

The 70D gives sharper images SOOC, due to a weaker AA filter.

this is kind of a crazy question.
7d is NOWHERE as good. The 7d has the absolute worst iso performance of any canon ive used. Grainy skies in well exposed iso 100? No thanks.
Seriously though, there is no reason to buy a 7d anymore, especially 7 current prices. its going on 5 years old, and still north of a grand- not a good investment at all.

I have just sold my 7D and replaced it by a 70D, and compared both carefully. The 70D has slightly better IQ than the 7D. My 7D was very good, unlike the one of the previous post (and I also have a 5DIII to compare both crops). The 70D really wins out in AF and live view over the 7D.

my opinion 70 D has better colors and gradients , more setting like digic 5+ better images on good light condition but 70D has more noise ever since low ISO

Uh oh. To clarify, you're implying the 70D has worse low ISO noise than the 7D?

+1. I tried a 70D in a store. I like it much better than the 7D. The ergonomics of the larger body and grip of the 7D, are probably preferred by 5D3 lovers...but other than that, I don't see a reason to buy a 7D now.
That said, I won't be buying a 70D anytime soon...until it gets discounted as much as the 6D has been recently. That would put a body-only price for the 70D down to about $800 or less. When that happens I might bite. Probably in November or December.

DxOmark scores also don't clearly show the nature of the noise.JumboShrimp said:
many 7Ds show patterned noise, especially in shadow tones
70Ds I've tested have much less pattern noise
random noise is OK, pattern noise is bad
no noise is even better but we're still waiting for Canon to catch up to everyone else on noise metrics.

Hi Guys!
We own both bodies. Summed up, the 70D is really the better body. The 7D was a hit when we bought it. But, as written by others, it has no good ISO performance. Compared, the 70D is there much better. The AF comes close to the 7D´s. And the pics are a little bit sharper.
My tip: Save the plus of about 100 Euro and buy an 70D.

For me it was the other way around. I decided end of last year to buy a 7D after comparing it with a 70D. I already own a 5D3 and from an ergonomic point of view the 7D body is a perfect match, the 70D clearly has a reduced feature set here. And since I only use the raw files I don't care about the better processing with newer DIGIC. Raw noise performance is no different between the two models. IMHO the only real advantages for the 70D are the new video features and the sooc picture quality. If you don't need any of those you get better build quality and better ergonomics with the 7D.

As I posted earlier, the big difference is in AF. The 7D's AF is far more erratic and has real difficulties on such combinations as the 300mm f/2.8 II with 2xTC. This has been corrected with the 70D, which is why I sold my 7D and bought the 70D. The other differences between the two are minor. N

You’ve tested sevral 70Ds?
In a lab or in the field?
Can you show some of your test results? I like to see the “real world” difference between the 7d and 70d and if there is any copy variation between the 70ds.
Aglet said:
No noise?
That would be great cause it would mean you could shoot in low light at iso 100 and 1/8000 second and just push the file 10 or 15 stops without any noise showing because there is none. But like all other impossibilities there is one “little” problem: it’s not possible.
By the way, “noise metrics” do not only apply to iso’s below iso 1600. Above iso 1600 Canon is on par or preforming better.

As I am fond of saying.... Who cares how many stops of dynamic range a blurry picture has.... Accurate focus is by far the most critical aspect in the search for better images... Nobody makes a sensor or lens that could have saved this shot....neuroanatomist said:

where can you find a camera that delivers no noise? if there is one that par with 70d or 7d specs, i would pay up 10K for that even though i like noise (note: noise that i add in, not from camera)

I used my 7d during last 3 years and after testing 70d i sold it and never regret. Better color reproduction, greater dynamic range, better noise structure (i hate 7d noise, it often destroyed shadows and uniform color surfaces), better and more reliable focus, better low light focus, video af is amazing, touch screen and wi fi is also very useful. The only downside - lack of magnesium alloy body

That is a bit of a silly question. Comparing the 70D against the 7D is like comparing a Ferrari 458 Italia to a Brick in a race. The 70D is much better.
The 70D is a 40 megapixel camera, with almost no AA filter, compared to a 18 megapixel camera that is 4 years older. The 70D has 9% less noise and delivers images that are 15% to 20% sharper, according to back to back tests.
I have owned 3 7D bodies, and currently have a 70D body. There is no comparison between the two. The 70D is way better.
For example you'll see lenses are 10 Mpix on the 7D on DXO, on the 70D they are 12 Mpix.
The 70D also has less noise at ISO 200 than the 7D has at ISO 100 so base ISO performance is incredible.
70D = 15-20% Sharper
70D = 9% less noise at LEAST at any ISO (in many cases there is a significant difference)
70D = 50% less noise at base ISO for landscapes
70D = Way better dynamic range at high ISO (same DR at low ISO)
70D = Way better color and tone
DXO scores are about as meaningful as taking the horsepower of a car, multiplying by it's price and dividing by it's model number. They're an arbitrary choice of combining numbers that have little meaning, you need to look at the actual data.
The image quality of the 70D is much better. The only reason you buy a 7D is if you need crazy autofocus and burst speeds for sports or action or incredible weather sealing. Otherwise the 70D just obliterates it.
